A syringe driving apparatus includes a housing, a driving member disposed in the housing and a resilient member connected to the housing and the driving member. The housing having a front end, a back end and a compartment between the front end and the back end, the compartment is configured to receive a plunger of the syringe therein. The driving member is movable relative to the housing between the front end and the back end. Movement of the driving member towards the back end deforms the resilient member to store potential energy in the resilient member, and upon release of the potential energy, the resilient member moves the driving member towards the front end to press the plunger to expel medicine out of the syringe.
